Dear Mam, Treatments of Polygonum and related genera (subfamily Polygonoideae) those by Haraldson and Ronse Decraene & Akeroyd, have segregated species of Polygonum in the broad sense adopted into two separate tribes, Polygoneae and Persicarieae. The remainder of Polygonum in the broad sense is generally assigned to Persicaria (or a varying number of segregate genera, such as Aconogonon and Bistorta) which, with Antenoron and Koenigia, comprises the tribe Persicarieae.
*Characters for segregation of Two species:* * * *Polygonum:* . Flowers axillary, solitary or in small clusters, sometimes forming lax leafy spikes. Perianth (4- or)5-parted, not enlarged in fruit. Stamens 5-8, reduced in number in outer whorl; filaments, especially the inner, strongly dilated at base. *Persicaria:* Inflorescence spicate, spikes usually several. Tepals fused for about 1/3 their length. Nectaries free, globular. Styles 1, bifid or trifid. Gurucharan Sir can be more useful for clarification. regards, On Wed, Sep 19, 2012 at 6:49 PM, ushadi Micromini <microminipho...@gmail.com > wrote: > now i am confused... > is perscicaria and polgonum the same? > > usha di > == > > On Wed, Sep 19, 2012 at 6:38 PM, Umeshkumar Tiwari <tigerumes...@gmail.com > > wrote: > >> yes it is also same >> >> >> On Wed, Sep 19, 2012 at 6:36 PM, Nidhan Singh >> <nidhansingh...@gmail.com>wrote: >> >>> Thanks Umesh Ji...I was almost sure this being P. amplexicaulis...the >>> only doubtful thing is the attached plant which is also identified as *P. >>> amplexicaul(e)is*....hope to get clarifications >>> >>> >>> -- >>> Regards, >>> >>> Dr. Nidhan Singh >>> Assisstant Professor >>> Department of Botany >>> I.B.
